This invention relates devices and more particularly tc aniimproved gas burner.

Anobject` of this invention is to provide av burner which-isconstructed. for use VAin heating "i plantso various types-and which is adapted to be used as a conversion f or converting 'a conventionalheater using coalor wood as affuelto a gas burning heater. Y

AAnother 1 obj ect of this invention is to provid-e "I a. burner. ofthis typdwhhis. so .OnS-tructedtha't the maximum amount of air is mixed with the gas prior to andat thetime sof ignitionof the gas.
